How can nativism best be described?

The correct answer is option:

-  Loyalty to old immigrants and discrimination against new immigrants.

Explanation:

Nativism refers to the ideology that protects the interests of a country's natives or existing inhabitants against those of new immigrants. On the basis of this interpretation, we can infer that the best description of nativism is "Loyalty to old immigrants and discrimination against new immigrants".We can understand the preference for the words "new immigrants" rather than natives because in many cases nativism applies to a country's "patriot" population rather than the original people of that country, take the U.S.A. for example, when we speak about natives we don't refer to the indigenous population as much as we do to the old immigrants taken as the forefathers of the United States.
